This C# SDK provides official support for the Model Context Protocol (MCP), enabling .NET applications to act as clients or servers for LLM interactions. It allows seamless integration of LLMs with diverse data sources and tools, benefiting .NET developers building AI-powered applications.

How It Works

The SDK implements the MCP specification, allowing .NET applications to discover, invoke, and manage tools for LLMs. It provides abstractions for client-server communication over various transports (like stdio) and facilitates tool registration via attributes ([McpServerTool]) or explicit configuration. This approach simplifies the integration of LLM capabilities into existing .NET ecosystems.

Quick Start & Requirements

• Installation: dotnet add package ModelContextProtocol --prerelease
• Prerequisites: .NET SDK.
• Resources: Minimal for client/server setup; LLM execution depends on the LLM itself.
• Documentation: API Documentation, Official Documentation, Protocol Specification, GitHub Organization.

Highlighted Details

• Supports both MCP client and server implementations.
• Enables tool definition via attributes for simplified server setup.
• Allows fine-grained control over server configuration and request handling.
• Designed for server-agnostic interoperability with any MCP-compliant server.

Maintenance & Community

Maintained in collaboration with Microsoft. Further community engagement details (Discord/Slack, roadmap) are not explicitly provided in the README.

Licensing & Compatibility

• License: MIT License.
• Compatibility: Permissive MIT license allows for commercial use and integration with closed-source applications.

Limitations & Caveats

This project is in preview, meaning breaking changes may occur without prior notice. Additional examples and documentation are planned for future releases.
